2 Claims.

Our invention relates to new anduseful improvements in locomotives, andmore particularly to the foundation ring or mud ring of the locomo tiverebox.

This invention contemplates and has for its principal object forming thegrate supports or bearer bars and mud ring integrally, and moreparticularly, it consists in forming the side and center grate supportsor bars and the side sections l0 of the mud ring integrally.

These and other objects and advantages will be recognized from thefollowing description and from the drawing, wherein Fig. 1 is a top planView of our integrally formed mud ring and grate bearer bars;

Fig. 2 is a section on line 2 2 of Fig. 1 with a portion of the iireboxconventionally shown;

Fig. 3 is a section on line 3 3 of Fig. 1; and

Fig. 4 is a section on line 4 4 of Fig. 1.

In the drawing there is shown conventionally, particularly in Figs. 2 to4, a locomotive rebox of usual form, having hollow end and side walls10. The hollow walls 10 are provided with a mud ring and indicated as awhole at 1l, comprising parallel side sections such as 12 and paralleltransverse end sections 13. The mud ring is formed with upstandingshoulders or llanges, namely, an inner ilange 14 and outer shoulder 15,said ilanges forming an integral part of the mud ring.

The inner sheet 16 of the rebox is attached to the mud ring at the innerside of the flange 14, and the outer sheet 17 of the rebox is attachedto the mud ring at the outer side of the flange 15. These sheets aresecured to the respective ilanges by riveting or in any other suitablemanner. At 18 is represented a side bearer bar for supporting the reboxgrate and at 19 a center bearer bar likewise used for supporting theiirebox grate. The grate bearer bars 18 and 19 constitute an integralpart of the mud ring 11 jointed at their ends with the flange 14 of themud ring. The bearer bars 18 and 19 are provided with recesses 20adapted to receive the trunnions of the grate sections, not shown, andsupporting them.

If preferred, the side bearer bars 18 can be eliminated and the gratesections at their sides supported from the side sections 12 of the mudring from circular projections or trunnions that may be formed therewithand each projection or 60 trunnion adapted to be received in acorresponding recess or seat in one of the grate sections. With thisform or" grate structure the recesses 20 of the center bar 19 would notbe used and in their place there would be provided circular projectionsor trunnions similar to those referred to for use with the side walls.

The mud ring and the grate bearer bars or supports may be cast in anydesired shape or form, and it is to be understood that the form shown inthe gures is selected merely to illustrate the invention. Numerouschanges in the details of construction may be made without departingfrom the spirit of our invention.

The integral construction of the mud ringor grate supports or bearerbars provides a stronger construction than the fabricated constructionheretofore in use. It further eliminates a number of parts and providesa simple construction which is readily made, cheap to manufacture andwhich will not work loose and require maintenance after the member isonce assembled in a locomotive rebox.

We claim:

l. In combination, a boiler comprising an inner and an outer sheet, amud ring for said boiler, a flange formed with and extending upwardlyfrom the inner marginal edge of said mud ringv and around the perimeterthereof, said boiler outer sheet being attached at its lower marginaledge to the outer side of said mud ring and said boiler inner sheetbeing attached at its lower marginal edge to the inner side of saidupwardly extending ange, and grate bearer bars formed with the outerside of said upwardly extending shoulder.

2. In combination, a boiler comprising an inner and an outer sheet, amud ring for said boiler having an inner and an outer upstanding flangeformed integrally with and extending around the perimeter of said mudring, said boiler outer sheet being attached at its lower marginal edgeto the outer sidev of said outer flange and said boiler inner sheetbeing attached at its lower marginal edge to the inner side of saidinner llange and grate bearer bars formed with the outer side of saidinner llange.
